Description of ctrk.klclick3[.]com
The domain ctrk.klclick3[.]com appears to be a tracking or click-routing subdomain associated with Klaviyo, an email marketing and customer engagement platform. The page title and screenshot show a branded Klaviyo 404 error page, suggesting this specific URL path is inactive or unavailable rather than serving primary site content. The available categorization data also places the domain in the information technology sector.
Based on the domain structure, this host may be used for campaign links, click measurement, or redirection within marketing emails and automated messaging workflows. Rather than functioning as a standalone public website, it appears to support backend or campaign-related infrastructure for a larger software service.
Safety Assessment for ctrk.klclick3[.]com
Scan results are mixed but lean relatively benign. Only 2 out of 92 security engines flagged the domain at the time of this scan, while the malware scan reported no flagged files and no malicious code was identified in the scanned content. Major blacklist checks were largely clean, although two threat-database entries showed generic suspicious or malicious-object style listings, which can indicate caution but are not, by themselves, conclusive.
Several contextual factors modestly reduce concern: the domain has existed for about 9 years, uses valid HTTPS, and the visible page is a branded 404 error page rather than a phishing form, download prompt, or deceptive storefront. The referenced links point to Klaviyo and a common frontend library, which is consistent with normal web application behavior.
That said, the presence of a small number of engine detections and two blacklist-style listings means some risk signals are present. Based on available scan data, this domain appears to be part of legitimate marketing infrastructure, but caution is still warranted for unexpected links. Based on these findings, no significant threats were detected at the time of this scan, though a limited number of security signals suggest monitoring may be appropriate.
Technical Description
The host uses a valid TLS certificate issued by Google Trust Services and is served through Cloudflare infrastructure at IP 104.17.94.1, with hosting geolocated to Canada based on available network data. Nameservers are on AWS Route 53, and the domain registration is long-standing, created in 2016 and currently set to expire in 2026. DNSSEC appears to be unsigned.
From a security posture perspective, the combination of HTTPS, established domain age, and mainstream CDN/proxy infrastructure is generally consistent with professionally managed web services. No malicious files, flagged outbound links, or iframes were identified in the provided scan data, though DNSSEC not being enabled means DNS responses do not benefit from that additional integrity layer.
